Sebastian Coe, president of World Athletics since 2015, was on Thursday re-elected as head of track and field's governing body on a third and final four-year mandate.
The 66-year-old, a two-time Olympic 1500m champion for Britain in 1980 and 1984, stood unopposed in the vote of the World Athletics Congress in Budapest, two days ahead of the start of the world championships in the Hungarian capital.
According to World Athletics rules, Coe will be unable to stand for a fourth mandate.
